int8 - conversion to one byte integer representation

int16 - conversion to 2 bytes integer representation

int32 - conversion to 4 bytes integer representation

uint8 - conversion to one byte unsigned integer representation

uint16 - conversion to 2 bytes unsigned integer representation

uint32 - conversion to 4 bytes unsigned integer representation

### Calling Sequence

  `y=int8(X)`
  `y=int16(X)`
  `y=int32(X)`
  `y=uint8(X)`
  `y=uint16(X)`
  `y=uint32(X)`

### Parameters

- `X`: matrix of floats or integers
- `y`: matrix of integers coded on one, two or four bytes.

### Description

converts and stores data two one, two or four bytes integers. These data types are specialy useful to store big objects such as images, long signals,...

  y=int8(X): return numbers in the range [-128,127]
  y=uint8(X): return numbers in the range [0,255]
  y=int16(X): return numbers in the range [-32768,32767]
  y=uint16(X): return numbers in the range [0, 65535]
  y=int32(X): return numbers in the range [-2147483648,2147483647]
  y=uint32(X): return numbers in the range [0, 4294967295]

### Examples

    int8([1 -120 127 312])
    uint8([1 -120 127 312])

    x=int32(-200:100:400)
    int8(x)
